Connectrix: Cisco MDS: Modulnulstilling Systemfejlkode 0x42b8001e fatal fejl.
Summary: Problemet opstår, hvor modulet nulstilles, og et par porte går i "hw_Failure"-tilstand. Det specifikke portinterval, der er identificeret, skal sættes i hardwarefejltilstand, men i stedet for at hele modulet genindlæses. Fejlen "F16_PLDA_RETRY_MERR" er en multibit ECC-fejl, uoprettelig hardwarefejl. ...

Cause
Den DEV_F16_CMN fejl på en switch i Cisco MDS 9000-serien indikerer typisk et hardwareproblem relateret til F16 ASIC. Denne fejl resulterer ofte i, at modulet genstarter på grund af en uoprettelig ECC-fejl (Error-Correcting Code) med flere bit.
Resolution
Den eneste måde at gendanne en grænseflade fra hw_Failure er at genindlæse modulet forstyrrende.
#reload module x
Hvis grænsefladerne er i en midlertidig hardwarefejl, kan status gendannes ved modulgenindlæsning. Hvis grænsefladerne har en permanent hardwarefejl, skal du fortsætte med moduludskiftning.
ADVARSEL: Aktiviteten er forstyrrende og bør udføres under vedligeholdelsesvinduet.
